HOPPER-DOOR-OPERATING DEVICE.

To alZ ie/tom it may concern lie it known that 1, Armor: L. LOGAN, a citizen of the United States, residing at Edwardsville, in the county of Madison and 5 State of Illinois, have invented a new and useful Improvement in Hopper-Door-Operating Devices, of which the following is a specification.

This invention relates to an operatlng mechanism for car hoppers and is especially 1' that type of car having a side rge. and in which one inclined l pper is stationary, the opposite side he lg hinged and movable.

35 The invention consists in the novel feacure. cmistruction hereinafter described,

pointed out in the claims, and shown in the accompanying drawi s, in which,

Figure 1 is a side e evation of a car with my device applied thereto. Fig. '2 is an end viewoi" the hopper with my device applied thereto, the sides of the car being in section, and the hopper door being in closed position. Fig. 3 a similar view the door being in open position. Fig. 4 is an. enlarged side elevation of an end portion of the hopper partly broken out, aguide-bracket being in section. said view looking from beneath the car toward the side carrying the hand-opera ing wheel. Fig. 5 is a section on the line of Fig. Fig. 6 is a section on the line 6-6 of Fig. :2.

In these drawings, 1 represents a car having a hopper which comprises a (low vardly and inwardly inclined fixed side 2 and a dowmvardly and inwardly inclined side 3 termed in longitudinal sections, the lower scction being hinged and adapted to swing why and outwardly. Oneytwb or these hoppers may be carried by j to the length of the car, i l have shown a car provided hoppers, and in such case v Y tll'lfl lg id in duplicate :ltilzlflflll each end he car. ."Vhere a car 1 out one oi such hopp rs only one ct operating parts is required and a" parts are duplicated in such a car as is --.;n in Fig i a description of the operatas for one hopper will suli'ice for he noted from Figs. 2 and 3, the

i tin car or any other suitable portion of in car supports adjacent the hopper in a iiizzl'p kOlfiClY arranged guide bar 5, and

upin the underside of said guide bar is fixed Specification of Letters Patent.

a bracket 6 which forms abearing for the inner end of an operating shaft 7 provided with a screw portion 8. Upon this portion.

8 works a thread block 9 the upper face of which" is broadened and flattened to bear upon the underside of the guide bar, said block sliding along said bar upon rotation of the shaft 7. The upper end portion of the shaft is journaled in the side of the car and its outwardly projecting end carries an operating wheel 10 and a ratchet 11, said ratche' being engaged by a gravity pawl or lock 12 suitably pivoted upon the outer face of the car. Upon the outer face of the hopper side '2, I arrange any desired number of bearings 13, in which I journal a shaft 14, said shaft projects slightly beyond an end of the hopper and the projecting end carries an arm 15 fixed upon the shaft to which is pivoted an angled end of a link 16, the opposite end of the link being pivotally connected to suit able lugs or .ears 1? formed upon the block 9. Mounted at suitable intervals upon the shaft 14 are depending arms 18. The lower ends of these arms have chains 19 connected to them, the chains being suitably anchored to the lower marginal portion of the swinging door section 4. i

It will be obvious from Figs. 2 and that when the hand wheel is rotated so as to turn the shaft 7 in one direction the block 9 will move from the position shown in Fig. 2 to the position shown in Fig. B'carrying a pivoted end of the link 16, with it.

This will rock the! shaft 1% causing the arms 18 to swing from the position shown in Fig. 2 to the depending position shown in Fig. 3 thereby permitting the door section l 'talling to open position by gravity. By revcrsing the direction of rotation the par s will more in opposite direction thereby lit ing the door +1- into closed position. and the gravity pawl. .12 will hold shaft 7 any accidental rotation.

Vvhat I claim is:-

l. The combination with a hopper h; ving a swinging side section, of a transversely aringed operating shaft having-a s rew portion, a thread block working upon said screw portion, a second shaft at right angles to the first mentioned shaft, an arm fixed upon the second mentioned shaft, a link pivotally connecting said arm with said block and chains opcratively connected respe tively to the swinging hopper section and to said second mentioned use.

2. A device of the kind described comprising a swinging door section, a shaft parallel thereto,iarms fixed Iipon said shaft, chains connecting said arms to said door, a

- second shaft arranged at right angles to the first mentioned shaft, said second shaft having a screw portion, a threaded block adapted to travel along said portion, means for operating the shaft, an arm fixed upon'the I first Inentioned shaft at an angleto the first 1 mentioned arms, and means lpiij otally .con-- necting said arm with said block, as and for the purpose set forth.
